"It's worth noting that the school data provided references "Brent International School - Manila," but the Wikipedia background describes "International School Manila" (ISM)."
These appear to be two distinct schools. The profile below is written based on the combined data provided, but parents should verify details directly with the school, as there may be a mismatch in the source information. International School Manila is a private, non-profit, non-sectarian international school with deep roots in the Philippines and a long-standing reputation for academic excellence. Founded in 1920 by a group of American and British parents living in Manila who sought a quality education for their children abroad, the school has grown over the past century into one of the most respected international institutions in Southeast Asia. Originally established as the American School, it adopted its current name in 1970, reflecting the increasingly diverse and globally minded community it serves. The school is situated in Bonifacio Global City, within the Fort Bonifacio area of Taguig — a modern, well-planned urban district that has become one of Metro Manila's most cosmopolitan neighborhoods. The location places families in close proximity to international dining, healthcare, retail, and a thriving expat community, making the transition to life in the Philippines considerably smoother for relocating professionals and their families. Academically, International School Manila offers a broad and rigorous program spanning prekindergarten through Grade 12, with instruction delivered entirely in English. The school follows an American-based curriculum framework and further enriches its upper-school program through the International Baccalaureate Diploma Programme (IBDP), giving older students the opportunity to pursue a globally recognized qualification that opens doors to universities around the world. This combination of American educational traditions and IB academic rigor makes the school an appealing choice for families who value both continuity with the American schooling experience and preparation for international higher education pathways. The student body at International School Manila is genuinely international in character, drawing children from a wide range of nationalities and backgrounds. This diversity is one of the school's defining strengths, fostering a community where cross-cultural understanding and global citizenship are not just aspirations but everyday realities. Families new to Manila can expect a welcoming environment where the experience of being an expat is widely shared and well understood. The school also benefits from its affiliation with the U. S. State Department's Assisted Schools program, which provides an additional layer of assurance for American families in particular regarding the quality and consistency of the educational experience offered. Additionally, International School Manila holds membership in the Interscholastic Association of Southeast Asian Schools (IASAS), one of only six schools in the region to hold this distinction. IASAS membership connects students to a vibrant network of competitive academic, athletic, and cultural events across Southeast Asia, enriching student life well beyond the classroom. For expat families arriving in Manila, International School Manila represents a stable, academically strong, and genuinely international community — one that has been welcoming families from around the world for over a hundred years.
